Can You Make a Wind Turbine Without Fossil Fuels?

wind-turbines-carboncounter
What is it made of? Lots of steel, concrete and advanced plastic. Material requirements of a modern wind turbine have been reviewed by the United States Geological Survey. On average 1 MW of wind capacity requires 103 tonnes of stainless steel, 402 tonnes of concrete, 6.8 tonnes of fiberglass, 3 tonnes of copper and 20 tonnes of cast iron. The elegant blades are made of fiberglass, the skyscraper sized tower of steel, and the base of concrete.

These requirements can be placed in context by considering how much we would need if we were to rapidly transition to 100% wind electricity over a 20 year period. Average global electricity demand is approximately 2.6 TW, therefore we need a total of around 10 TW of wind capacity to provide this electricity. So we would need about 50 million tonnes of steel, 200 million tonnes of concrete and 1.5 million tonnes of copper each year. These numbers sound high, but current global production of these materials is more than an order of magnitude higher than these requirements. (Source: Read more)

Wind Power’s Toxic Embrace

stopthesethings.com
If clean, safe and efficient energy is to be our standard, then why use wind power at all?

When we examine the entire process, the construction and operation of wind turbines is a dangerous and toxic affair. It begins with the mining of rare earth minerals, a collection of chemical elements manufactured mostly in China. The ill-protected workers are exposed to hazardous materials like hydrofluoric acid and radioactive particles. These substances are then exported worldwide, for use in wind turbines as well as computers, cell phones, hybrid cars and energy saving light bulbs.

The process of refining of these elements leaves death and destruction in its wake, polluting farmland, killing livestock, seeping into waterways and poisoning drinking water. Besides the devastation to the environment, nearby villagers report significant health problems, like bone, respiratory and heart diseases. Some residents suffer helplessly while their teeth fall out. But, since all this is occurring in the Far East, Western environmentalists don’t seem particularly concerned. (Source: Read more)

Concrete Turbine Base

Cement is one of the worst elements created by man as regards carbon footprint. This base will never be removed, but simply covered over at the end of the wind farm’s life. The damage to the ecosystem, water run-off and the peat moorland that it displaces will remain for millennia. (Source: Concrete Turbine Base)

How Much CO2 Gets Emitted to Build a Wind Turbine?

Stop These Things IWT's CO2 Emits

Even before the blades start spinning – the average wind farm clocks up thousands of tonnes of CO2 emissions: “embedded” in thousands of tonnes of steel and concrete. So, every wind farm starts with its CO2 abatement ledger in the negative.

Here’s Andy’s Rant with a breakdown of just how much CO2 goes to build one of these things.

So what’s the carbon foot print of a wind turbine with 45 tons of rebar & 481m3 of concrete?

Its carbon footprint is massive – try 241.85 tons of CO2.

Here’s the breakdown of the CO2 numbers.

To create a 1,000 Kg of pig iron, you start with 1,800 Kg of iron ore, 900 Kg of coking coal 450 Kg of limestone. The blast furnace consumes 4,500 Kg of air. The temperature at the core of the blast furnace reaches nearly 1,600 degrees C (about 3,000 degrees F).

The pig iron is then transferred to the basic oxygen furnace to make steel.

1,350 Kg of CO2 is emitted per 1,000 Kg pig iron produced.

A further 1,460 Kg CO2 is emitted per 1,000 Kg of Steel produced so all up 2,810 Kg CO2 is emitted.

45 tons of rebar (steel) are required so that equals 126.45 tons of CO2 are emitted.

To create a 1,000 Kg of Portland cement, calcium carbonate (60%), silicon (20%), aluminium (10%), iron (10%) and very small amounts of other ingredients are heated in a large kiln to over 1,500 degrees C to convert the raw materials into clinker. The clinker is then interground with other ingredients to produce the final cement product. When cement is mixed with water, sand and gravel forms the rock-like mass know as concrete.

An average of 927 Kg of CO2 is emitted per 1,000 Kg of Portland cement. On average, concrete has 10% cement, with the balance being gravel (41%), sand (25%), water (18%) and air (6%). One cubic metre of concrete weighs approx. 2,400 Kg so approx. 240 Kg of CO2 is emitted for every cubic metre.

481m3 of concrete are required so that equals 115.4 tons of CO2 are emitted.

Each turbine blade is made of glass fibre reinforced plastics, (GRP), i.e. glass fibre reinforced polyester or epoxy and on average each turbine blade weighs around 7,000 Kg each.

Each turbine has three blades so there’s 21,000 Kgs of GRP and each blade can be as long as 50 metres.

A typical wind farm of 20 turbines can extend over 101 hectares of land (1.01 Km2).

Each and every wind turbine has a magnet made of a metal called neodymium. There are 2,500 Kg of it in each of the behemoths that have just gone up around Australia. (Source: Read more: How Much CO2 Gets Emitted to Build a Wind Turbine?)

Maintaining Turbine Efficiency: Guarding Against Premature Wear

Author Roger Simonson concludes by saying that “Wind is a great environmentally friendly energy source [we dispute that: ed.], but only so far as the power produced. The manufacturing and disposal of the depth media filers [sic, he means filters] used in these turbines is damaging to the environment. Over 80% of these filters end up in landfills—all of which contains four to six ounces of oil that seeps into the ground waters of our landfill sites.” (Source: Maintaining Turbine Efficiency: Guarding against premature wear)

Greens’ silence on folly of wind and solar power

newsweekly.com
Wind farms have the life of a parasite because they freeload themselves onto existing grids paid by conventional efficient energy, need subsidies and drain electricity from the grid when it is too cold. Wind turbines don’t run on wind; they run on subsidies.

A single 1,000-megawatt wind farm produces at least 7 million tonnes of carbon dioxide in component construction and concrete. Almost 100,000 truckloads of concrete are required just for the footings. Maintenance by diesel-powered vehicles only adds to emissions. Wind farms need 24/7 back-up from carbon dioxide emitting coal-fired power stations.

Wind farms do not reduce human emissions of carbon dioxide; they increase emissions.

A wind farm using 660-kilowatt generators requires 7,600 generators at 20 per cent efficiency to produce 1,000 megawatts. At $2,000 per kilowatt installation, this would cost $10 billion. This is more than twice the cost of a reliable, clean, coal-fired 1,000-megawatt generator. (Source: Read More)

Wind turbines not only attract and kill raptors, hirundines and bats: they make people seriously ill, and they contaminate the environment.

“Scotland’s environmental watchdog has probed more than 100 incidents involving turbines in just six years, including diesel spills, dirty rivers, blocked drains and excessive noise.

“Alarmingly, they also include the contamination of drinking water and the indiscriminate dumping of waste…”

“In another incident in November 2011, 1,000 litres of oil leaked from a turbine at the Clyde wind farm in Abington, Lanarkshire, resulting in an emergency clean-up operation.” (Source: Read more)

Wind Energy’s Ghosts

The taxpayers who paid for the subsidies to build the wind farms, then paid over the odds for an unreliable source of power generation will ultimately be left to pick up the bill for clearing up the Green eco mess. (Source: 14000 Abandoned Wind Turbines In The USA)

Britain to Halt Onshore Wind Projects – Wind Farm Impacts May Be Worse Than Climate Change

Referring to wind farms and climate change, UK Environment Secretary Owen Paterson added that “some of the steps we are taking might actually cause more damage than the original problem itself.” Wind projects, he added, “blight rural lives” and have, among other negative environmental effects, “significant impacts on the rural economy and the rural environment.” (Source: Britain to Halt Onshore Wind Projects: ‘Wind Farm Impacts May Be Worse Than Climate Change’)

In China, the true cost of Britain’s clean, green wind power experiment: Pollution on a disastrous scale

“Toxic lake poisons Chinese farmers, their children and their land. It is what’s left behind after making the magnets for Britain’s latest wind turbines… and, as a special Live investigation reveals, is merely one of a multitude of environmental sins committed in the name of our new green Jerusalem” (source: In China, the true cost of Britain’s clean, green wind power experiment: Pollution on a disastrous scale)
